The Pitch

Let's move to a modern approach for our developer documentation and, generally, improve developer experiences by creating a focused developer portal. Let's unify our documentation efforts, use documentation to reduce customer success needs, use documentation to improve experiences, and create a one-stop-shop for anything a developer might need. Additionally, lets make it conceptually simple and easy to maintain and support. This idea is not new, in fact nearly every modern API company uses this approach:

• http://developers.hubspot.com/
• https://developer.salesforce.com/
• https://developer.intuit.com/
• https://developers.google.com/

# Example of multiple key AES encryption for text files using the openssl v. 0.9.8+ command line utility
# Uses n public certs as key for MIME PKCS envelope, any individual private key can decrypt.
#
# If standard RSA ssh keys exist, these can be converted to public certs as well (and ssh keys can decrypt)
# 
# To sign (and verify) the encrypted file, one of the private keys is required, see:
#    http://www.openssl.org/docs/apps/smime.html#EXAMPLES for openssl smime examples
# or http://www.openssl.org/docs/apps/cms.html#EXAMPLES for cms utility (OpenSSL v. 1.0+)

# HubCrypt
# ========
#
# Decrypt a file encrypted using hubencrypt (ok, it's just openssl + rsautl +
# your SSH keys). It needs the private key that matches your last public key
# listed at github.com/<user>.keys

# unregister broken GHC packages. Run this a few times to resolve dependency rot in installed packages.
# ghc-pkg-clean -f cabal/dev/packages*.conf also works.
function ghc-pkg-clean() {
  for p in `ghc-pkg check $* 2>&1  | grep problems | awk '{print $6}' | sed -e 's/:$//'`
  do
    echo unregistering $p; ghc-pkg $* unregister $p
  done
}

# remove all installed GHC/cabal packages, leaving ~/.cabal binaries and docs in place.
